Dr. Colosso

Formerly a powerful supervillain, Dr. Colosso was defeated by Hank Thunderman and turned into a talking bunny that now lives with Max in his lair. He hopes to get back to his old trouble-making line of work one day, but in the meantime, Dr. Colosso offers advice to his devoted Max and spurs him on to loads of mischief.
